我尝试用vscode安装android SDK来编写flutter。但每当启动 Android 模拟器时，它都会要求许可证。但每当我使用命令 flutter doctor android 许可证时。它给了我这个错误。我正在使用，
ANDROID SDK 平台工具 - 29.0.6
ANDROID SDK 构建工具 - 29.0.3
ANDROID 7(API:24)
flutter doctor

我尝试了很多 StackOverflow 解决方案，但没有成功。也许已经过时了。
flutter doctor --android-licenses
Error: Unknown argument --licenses
Usage:
sdkmanager [--uninstall] [<common args>] \
[--package_file <package-file>] [<packages>...]
sdkmanager --update [<common args>]
sdkmanager --list [<common args>]
In its first form, installs, or uninstalls, or updates packages.
<package> is a sdk-style path (e.g. "build-tools;23.0.0" or
"platforms;android-23").
<package-file> is a text file where each line is a sdk-style path
of a package to install or uninstall.
Multiple --package_file arguments may be specified in combination
with explicit paths.
In its second form (with --update), currently installed packages are
updated to the latest version.
In its third form, all installed and available packages are printed out.
Common Arguments:
--sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool
--channel=<channelId>: Include packages in channels up to <channelId>.
Common channels are:
0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).
--include_obsolete: With --list, show obsolete packages in the
package listing. With --update, update obsolete
packages as well as non-obsolete.
--no_https: Force all connections to use http rather than https.
--proxy=<http | socks>: Connect via a proxy of the given type.
--proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use.
--proxy_port=<port #>: Proxy port to connect to.
* If the env var REPO_OS_OVERRIDE is set to "windows",
"macosx", or "linux", packages will be downloaded for that OS.
那么如何激活android SDK的许可证呢？
最佳答案
当我运行flutter doctor --android-licenses时，我遇到了同样的问题。我在没有使用 Android Studio 的情况下安装了 android SDK。
这是我为使其发挥作用而采取的步骤
- 我去了android studio download page向下滚动并下载适用于我的操作系统(Windows)的命令行工具
- 然后我将其解压到
android-sdk目录 - 我在
cmdline-tools中创建了一个名为latest的新文件夹，并将cmdline-tools的内容移至其中。
此后，我尝试运行flutter doctor --android-licenses，然后它运行没有错误，并在我的设备上运行它没有问题。
